WINDOW-SASH PIVOT..

Specification of Letters Patent.

Patented Jan. 30, 1906.

Application filed April 26, 1905. Serial No. 257,429.

To all whom t may concern:

Be it known that I, PETER J. @Aoi-IAT, a citizen of the United States', residing at Louisville, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Window-Sashes; and I do hereby declare that the following is a full, clear, and exact description of the saine.

The present invention relates to windows having the sash horizontally pivoted to strips on each side, which strips are adapted to be moved. laterally and. to move longitudinally in the groove of the window-frame; and the objects of the invention are to provide pivotal connections which will at all times draw and hold the strips tightly against the side edges of the sash-strips and to provide spring arms or members detachably connected to the strips and rollers secured thereto adapted to bear against the seats of the grooves in which the strips move or travel; and another obj ect of the invention is to provide a pivotal connection between the strips and the metal-faced. sashes that is capable of allowing the metal-faced sashes and strips to part or move away from each other sufficient to unseat the ribs normally seated in the corresponding grooves.

In the accompanying drawings, Figure 1 is an elevation of one side of a window and its frame, partly in section, showing the different parts properly arranged and connected. Fig. 2 is a detached view of one of the springs and its roller. Fig. 3 is a view showing a portion of the movable strip, its pivot-plate, and spring. Fig. L1 is a view showing a portion of a window-sash with its metal-lined face.

Similar numerals of reference indicate corresponding parts in all the 'figures of the drawings.

In the accompanying drawings, 1 represents the window-frame, which is of the usual construction, and. in which frame are secured in the usual manner the window-sash frames 2. To the outer vertical edges of the window-sash frame are attached the metal strips 3, which metal strips are provided with the ribs 4 and the groove 5, which ribs and groove lit upon the corresponding rib and grooves formed upon and in the vertical edges of the vertical sash-rails, thereby providing a metalfaced sash-rail. To the vertical sash-rails of the sash-frame 2 are connected the metallic strips 6, which metallic strips are what might be termed channel-bars, the flanges of said channel bars fitting the sides of the grooves" in the windowframe, in which grooves said stri as or channel-bars move. To the vertical rails of the sash-frame 2 are attached the plates 7, which plates are seated in the wood of said sash-rails, as best illustrated in Fig. 1, and over which plates the metal strips 3 are placed, thereby providing a uniform contact as between the strips or channel-bars 6 and the metal strips 3. To the plate 7 is attached or formed integral therewith the short stud 8, which short stud extends through the metal strip, as best illustrated in Fig. 4L. To the strip or channel-bar 6 is attached the plate 9, which plate is provided with the open flaring flange 10, which open flaring il ange is Y rovided with the smoth rim 11, and upon w lich rim rests the spring 12, which spring spans the flaring flange 10, as illustrated in Fig. 1. The stud S is provided with the reduced portion 13, which reduced portion is extended through the aperture 15 in the spring 12 and its outer end headed, so as to properly connect the spring 12 to the extension 13 and the stud 8. Vhen the spring is straight, as illustrated in Fig. 1, it is free to rotate upon the extension 13, but when the spring is bent it may bind upon said extension, at which time the spring rides upon the rim 11.

By providing the flange 10 with the smooth rim 1 1 the spring 12 will be free to rotate with the stud 8, thereby preventing any wearing of the small extension 13 from time to time as the window-sash is turned upon its pivotal points.

It is well understood that when the window-sash frame is rotated there must necessarily be a parting between the channel-bars 6 and the strips 3 for the purpose of unseating the ribs and the grooves, said. channel-b ars being provided with the grooves 16 and the rib 17, corresponding substantially in shape with the ribs and groove formed in the metal plate 3, and in order to allow for this parting a pushing away from the metal strips of the channel-bars 6 and at the time the channelbars 6 are moved laterally the spring 12 will be bent inward, with its ends resting upon the rim 11, at which time the springs are free to turn upon the rim, providing the condition of said spring is such that no relative movement takes place as between the stud 8 and the spring, thereby preventing any wearing of the arts or cutting away of the necessarily sma ler extension 13.

IIO

It is well understood that in Windows of the class described there should be at all times a close contact as between the channel-bars 6 and the metal strips 3 when the window-sash is in its normal condition, and for the purpose of accomplishing this the springs 18 are provided, which springs are formed of spring metal and with the hooked ends 19, which hooked ends are located under the bar 20, which bar is securely connected to the channel-bar 6.

For the purpose of placing the spring 8 in position Yto act as a spring the cross-bar 21 is provided, and over which cross-bar islocated the spring 18, as illustrated in Fig. 1. The free or grooved contact end of the spring 18 is provided with the antiriction-roller 22, which antiirictionroller travels or rolls upon the seat ofthe roove. The bar 21 also serves the purpose o providing a means for connecting the weight-cord 23, as illustrated in Fig. 1. The spring 18 should be so formed that it will allow the channel-bars to move laterally at the time the sash-trame is rotated and to bring the channel-bar snugly against the strip 3 when the window-sash is brought into its normal position. Y

It is well understood that in rotating the window-sash from time to time upon its pivotal points there is necessarily more or less Wear as between the parts, and if the parts are formed of wood the ribs will soon wear away, so that there is a looseness as between dow-frame, and a sash-frame, the vertical i rails 'of the sash-frame provided with metal strips having ribbed and grooved faces, channel-bars or strips, located adjacent and in normal contact with the metal strips upon the vertical members of the sash-frame, and provided with ribbed and grooved faces, plates located between the metal strips and vertical sash-rails and provided with studs extended through the metal strips, said studs having reduced end portions, plates secured to the channel-bars and provided with open flaring anges having smooth rings, springs adapted to span the ianged openings and the springs secured to the reduced portions ofthe studs, substantially as and for the purpose speciiied.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
